Deperming has critical importance and can't be ignored. This process is different from the types of Degaussing as it nullifies permanent magnetic field

The potency of a magnetic field is measured in terms of Gauss. And therefore, by definition,  degausse means to reduce/eliminate the strength of the magnetic field. Degaussing coils are used to reduce the effect of Earth magnetic field on the ship’s magnetic field. A magnetic...

The Earth’s magnetic field is the cause of the ship’s permanent magnetic field. The process of constructing a ship in the Earth’s magnetic field generates an appreciable amount of permanent-magnetism in the floating metal structure. Whenever there is a movement of the floating metal structure,...
